Battery Precautions
Observe the followings when handling the
battery.
WARNING!
• Stop the engine and turn the main starter
switch to the "OFF" position when
checking/handling the battery.
• Wipe off the dust accumulated on the top of
the battery with moistened cloth.
• The battery produces hydrogen gas,
involving the explosion hazard. Do not put
fire such as cigarettes close to the battery
or take any actions that can cause sparks.
• The battery fluid is diluted sulfuric acid,
which corrodes clothes and skin. Should
the battery fluid come into contact with your
clothes or skin, wash the affected area
immediately with plenty of water.
Should it go into your eye, wash your eye
immediately with clean water and consult a
physician.
• Wear goggles and rubber gloves when
handling the battery.
• Disconnect the ground side (normally (-)
terminal) first to remove the battery, and
conversely, connect the (+) terminal first to
install the battery.
Objects such as tools coming between (+)
terminal and the machine body will cause
sparks.
• Slackened battery terminals can cause
sparks with poor contact, involving
explosion hazard. Tighten securely when
Installing the terminals.
• Secure the battery when changing the
battery to prevent the battery from being
displaced. If it is not secured, the terminals
will slacken, causing sparks.
